A quick patch release to address a few critical and minor issues that came up in 1.2.0.

1.20.1

• New Datapack Authors: replace_first property has been added to the egg loot modifier object. Check the wiki for details.

• Fixed an issue where vertical flight speed was incorrectly calculated with the camera based driving.
• Lazy resolution of random breeds for dragons and eggs is now at the latest possible opportunity, to prevent unnecessary resolving during early querying and prevent incorrect breed assigning. Also fixes a crash where the client would resolve a breed and create unsafe thread invoking of a RandomSource (clients go boom).
• Fixed a potential issue with servers accessing client only code.
